I need to replace the connector on my trailer. It is at the camp but I just know its a 5 pin connector. Can someone tell me what the difference is between these two? Looks like one has 6 wires and one has 5 but they are both 5 pin. I am not sure how many wires I have. Wanted to order before this weekend but may just wait and see exactly how many wires I have.

Not on my monitor. After closer review they do both have blue.

Brown is tail light.
Green is right turn.
Yellow i left turn.

So it looks like the one on top has a black and white whereas the one on the bottom just has a white. Both 5 pins though.

I guess I may need to look at exactly how many wires I have before ordering.

How expensive are they? If less than $10, I'd just order both.

The first one has two brown wires (tail lights) to connect one to each side. Green-brown for right and yellow-brown for left. Either will work.

Reverse Light for a flat 5 pin plug. Brake for round 5 pin plug.

The difference is related to the taillights. The harness with 6 wires has two brown wires for the taillights, 1 left, 1 right.

I'd second this. Either would work. With the 5 wire one you would need to connect both tail lights to the same brown wire. With the 6 wire one, you have a dedicated one for each. I'm tired of hassling with grounding issues on trailers that last time I rewired a trailer, I just went ahead and ran a ground wire to each light. It's extra work and probably overkill, but I know it's grounded.

Be careful with loaning our trailers. A relative borrowed my gooseneck flatbed to haul some concrete bunker silo sections and he came back to the house complaining that it was too hard to pull up the driveway. His Ford pickup had a bastard wiring connection and the constant power wire was connected to the brake terminal. Unplugged the cord and it pulled fine. He said he would just use it without the connector plugged in and took off. Two months later it came back and those new brakes that it had gotten not too long before he borrowed it were burned out completely. Seems as though his brother did the driving with that pickup and obviously thought that it was just a heavy load. No apologies and no repairs. Typical of loaning things out to relatives.

Ford uses a standard pinout for a 7 pin layout (assuming that is what they trailer had). Was this some home wired thing?

One has 2 brown wires for parking lights the other plug has only 1 brown wire for parking lights on the trailer. The plug with 2 brown wires is for 1 wire to run down each side of the trailer to attach to each parking light. The other plug runs only 1 wire down the trailer frame and ran across the back of the trailer to the other park light. If you have several amber running(park) lights it may be easier to run 2 seperate brown wires.

I was able to have someone check the wiring on my trailer. I do have 2 browns (6 total) so I ordered that adapter and just had it shipped directly to the camp arriving tomorrow. I do have a few amber parking lights down the side of the trailer so you are correct. Thank you all for the responses.
